This invention relates to cookers, and more particularly to portablecookers which are adapted to be carried about while still maintainingtheir contents in heated condition.

In the past, it has been desirable to have cooking devices in which foodmay be heated and moved from place to place while still keeping the foodin a heated condition. It has been a common practice to cook food at onepoint in containers, and to carry it to a remote point at which place itis reheated for use. One of the objects of this invention is to avoidthe need for reheating, by providing means for maintaining the food in acontinuous heated condition.

Another object of the invention is to provide a portable cooker arrangedto carry its own heating means.

A further object is to provide a cover construction which will precludethe cover from being 20 easily knocked off of the cooker.

Yet another object is to arrange the handles of the cooking device sothat they can cooperate with the cover to lock the same in place andavoid splling the contents of the cooker.

Still another object is to provide a cooking utensil with a separablepart which automatically provides proper air circulation for completeand efiicient combustion.

Other objects and advantages of the inven- 80 tion wiil be ascertainedfrom the following description, taken in connection with theaccompanying drawing.

In the drawing, wherein like reference characters indicate correspondingparts in the various 35 figures:

Figure l is a side sembled relation;

Figure 2 is a cross-section of the device substantially on a line 2--?.of Figure 1;

Figure 3 is a top plan view showing the removable grill; and

Figure 4 is a partial perspective showing the cooperating relationbetween the handles, the cover, and the cooker.

Considering the drawing in greater detail, the device comprises areceptacle iii, a cover i2, and a base heating compartment is.

The base is arranged with a substantially cylindrical center element itspot-welded at ap- 50 propriate points it on the bottom of the heatingcompartment, to provide a means for retaining a heating medium such asthe well-known so-called canned heat or Sterno. ihe side walls of theelevation of the device in asheating compartment are provided with oneor 55 more series of openings, with the openings 10- 5, 1939, Serial No.258,517

cated on opposite sides of a diameter, and ent series at differentelevations.

In Figure 1, a series of three openings 28 in one side wall of thecontainer are shown substantially on a merit l6, and with a secondsimilar series 22 at the same elevation and at the opposite side.Similar series of openings 24 and 2'. in the side walls are arrangedabove the first described series of air vents, and are positioned justbelow the base 28 of the cooking compartment it! and disposed ninetydegrees with respect to the other series of openings. By means of thisarrangement, continuous air circulation through the heating compartmentcan be maintained so that complete combustion and efficient heating willalways be maintained.

The cooker comprises a substantially cylindrical receptacle iii, havinga side wall which is ribbed or beaded 36, so as to rest upon the rolledtop 32 of the heating or base compartment. The upper edge 35 of thereceptacle is beaded or rolled in a manner similar to the upper edge 32of the base heating compartment.

Channel shaped handles 35 are preferably spotwelded at 38 to thereceptacle, and are located on opposite sides of a diameter of thereceptacle.

The cover l2 has a handle 40 of channel crosssection, which is alsospot-welded to it. The cover is flat, having a relatively deep side wall42 which fits snugly against the bead 3A.

A pair of bails or handles it are fastened to eyes it spot-welded to thebase member at spaced points, which are slightly off center or" adiameter.

- The calls are so arranged and designed that they will firmly engagethe cover in the vicinity of the points 58, thereby locking the coverfirmly on the receptacle, whereby the device may be carried. Joltingthen cannot spill the contents.

It is preferable to form the various parts, of suitable metal, and inthe preferred form an enamel coating may be placed entirely over thedifferlevel with the top of the ele- 5 surface of the same, which may ifdesired, be of demonstrate food products,

apertures.
